Solid Snake is dispatched at the request of Colonel Roy Campbell to penetrate the terrorists' defenses and neutralize the threat. Snake is also ordered to locate hostages DARPA Chief Donald Anderson, and ArmsTech president Kenneth Baker. Colonel Campbell's niece, Meryl Silverburgh is also held captive in the facility after refusing to take part in the uprising. Snake enters the facility and locates the DARPA Chief in a cell. He informs Snake of the new Metal Gear REX unit housed at the facility, but then suddenly dies of what appears to be a heart attack. Meryl, who is held in adjoining cell, manages to break out and assists Snake in his escape as enemy soldiers are alerted to his presence. Snake then finds the other hostage, Kenneth Baker. Revolver Ocelot challenges Snake to a gunfight, which is interrupted by a mysterious cyborg ninja who cuts off Ocelot's hand. Baker briefs Snake on the Metal Gear project and, like the DARPA Chief, suddenly dies of a "heart attack".
